NiSi 49mm Highlight Diffusion (HDF) Pro Nano Filter

Cinema-grade manufacturing process uses advanced micro-lens technology to diffuse bright areas, adding a smooth finish to highlights and recreating the timeless look of classic film. Perfect for creating dreamlike visuals with a cinematic touch.

Film-Inspired Highlight Diffusion

The micro-lens technology evenly diffuse highlights across bright areas (such as skin highlights, light sources, or reflective surfaces), creating a mellow, film-like glow. This creates the same natural halation effect seen in traditional film, adding depth and emotion to every scene without overexposing details.

Contrast-Preserving Clarity

Unlike standard Black Mist filters that flatten contrast, the HDF's advanced design maintains the original tonal balance. Shadows remain rich, and mid-tones stay vibrant, ensuring images retain their dynamic range even in challenging lighting conditions.

Multi-Layer Nano Coating

Both sides feature a multi-layer nano coating that combines anti-glare properties and waterproof & oil-resistant protection, reducing lens flare and ensuring protection and easy maintenance in harsh environments.

Durable Brass Construction

Crafted from high-quality brass, the filter frame is resistant to corrosion and wear over time. The precise machining ensures a secure, seamless fit with lens threads. Its low thermal expansion maintains stability even in extreme temperature changes.

49mm Thread Compatibility

Engineered with a standard 49mm threaded mount, this filter fits seamlessly onto standard 49mm threaded lenses.

Ideal for photographers and filmmakers who want timeless beauty in every shot.
